Question : A chord is drawn in a circle of radius 10 cm, if the distance of the chord from the centre is 6 cm, then the length of the chord (in cm) is:
Option 1: 10
Option 2: 12
Option 3: 16
Option 4: 8
Correct Answer: 16
Solution : In $\triangle AOS$, AO is the radius. ⇒ $AO = 10$ cm It is right-angled at S, Applying Pythagoras theorem, we get, $AO^2=OS^2+AS^2$ ⇒ $10^2=6^2+AS^2$ ⇒ $100-36=AS^2$ ⇒ $AS^2 = 64$ ⇒ $AS=8 $ cm Now, $AS = \frac{1}{2}×$ Length of the chord ⇒ Length
